Thanks. There's a travel prepaid credit card for Canadians that lets me convert the funds on the card to Euros and therefore pay in Euros, that's why I ask.
You’ll have zero problems, the machines don’t differentiate. A prepaid card works exactly the same as a credit card except that the available funds are limited to what is actually on the card at the time.
That’s exactly what the Wise card that I suggested above does and is. I use the Wise card, because I can load whatever currency on it that I require ( it's currently loaded with Norwegian Krone, Sterling and euro.The card automatically draws from the currency balance in the country concerned, so Sterling in England or Euro in Europe)..
I limit the funds on it for additional security ( max €500). I can transfer additional funds almost instantly using the app, lock or unlock the card at will, use it to withdraw cash at an ATM, but also in place of a credit card online.
In addition to this I can track not only how much I've got left but everything I spend because it all shows on the app. And yes it's also 'tap and go'.
I transfer the funds to it from my credit card, which I'm carrying for this purpose and as a backup. ( Obviously I keep it separately). The fund transfer is recognized by the credit card company as a purchase, so I also get my points.
In addition to which the Wise card invariably has one of the best exchange rates available. There is no additional transfer fee, and ZERO fees for purchases.
The only potential limitation is that only the first two cash withdrawals in a month are free, I think to a total of 600 euros. But when you consider that in Spain on the Primitivo I spent €200 in two weeks, including paying my share for 4 dinners in cash so that others could pay by card, that is more than sufficient.
There is a small one off purchase cost, I think it was €9.
If your prepaid travel card does all of that then go for it!
Edited to add: it also pays interest on the money that you hold on the card. Considering that I never have much I don't get much but it's still better than nothing!
